Application filed November 16,1904. Serial No. 233,006.

To all whom it may concern:

Be it known that I, HIRAM BLAISDELL, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Manual Distributing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to means for operating upon filtration plants or filters, and particularly to means constructed to operate upon partially or entirely covered filtration plants or slow sand filters; and some of the objects of the invention are to provide means of this general character which are simple and cheap in construction and easy and inexpensive in operation.

Another object of the invention is to provide means for discharging filtering material in or throughout filters.

A further object of the invention is to provide means so constructed as to be capable of movement over the entire surface of the filter and around or adjacent to the piers or supports for the covering of the filter or around other obstructions in the same.

Still another object of the invention is to provide means for conveying or supplying filtering material to the machine throughout the movement of operation thereof and also to provide means upon the machine to discharge the material so supplied thereto.

Furthermore, an object of the invention is to provide means for conveying or supplying filtering material to the machine by means of a fluid under pressure and for separating the conveying fluid or element from the filtering material and discharging the fluid.

Another object of the invention is to provide means for distributing or discharging material constructed to be supported and travel upon the surface of the filter during the operation of the machine.

With these and other objects in view the invention consists, essentially, in the construction, combination, and arrangement of parts, substantially as more fully described in the following specification and as illustrated in the accompanying drawings, form-- ing part of this application, in which Figure 1 is a top plan view of a'machjne,

partly broken away. Fig. 2 is a longitudinal central sectional view of the same, and Fig. 3 is a perspective view of a modification thereof.

Similar characters of reference designate corresponding parts throughout the several views.

This invention is particularly designed and adapted for use upon filtration plants or slow sand filters, which are partially or entirely covered or roofed over, although the invention is equally well adapted for use upon open filters and for other purposes. However, in this application the invention will be described in connection'with or as operating upon slow sand filters.

Referring to the drawings, the reference character 1 designates a frame or structure of any suitable form, size, and material, in or upon the lower ends of which are preferably mounted supporting-shafts 2, desirably carrying sets of sprocket or toothed wheels or rollers 3, over which pass chains or belts 4, to the links of which are preferably attached strips or plates 5, thereby forming a flexible traveling support or base for the machine, constructed to rest upon the surface of the filter operated upon and to effect a uniform distribution of the weight of the machine over a large surface of the filter to prevent injury thereto, as will be readily understood by those skilled in the art to which this in vention appertains. 4

The propulsion or travel of the machine over the filter is preferably effected by means of an electric motor 6, suitably mounted upon a support or bracket 7, formed on or connected with the frame 1 of the machine, the motor being provided with suitable connections with the source of electrical supply, and the driving-shaft 8 of the motor carries a pinion 9, desirably meshing with a large gearwheel 10 on a propelling-shaft 1 1, mounted in suitable bearings 12 upon the frame 1, and preferably a sprocket-wheel '13 is connected .by a sprocket-chain 14 with a large sprocketwheel 15 on one of the supporting-shafts 2, substantially as illustrated in Fig. 1 of the drawings.

Preferably mounted or secured within the -frame 1 is a receiver or hopper 16, desirably having inclined sides 17, Fig. 2, and a partial partition or division plate 18 extending nearly to the bottom of the receiver, to or conveyed from the machine to any desired place of deposit.

The filtering material is preferably conveyed to or discharged into the machine through a flexible or other pipe or connection 22, having removable connection 23 with a discharge spout or nozzle 24, terminating within the receiver 16 and preferably between the side wall 17 thereof and the partial partition 18, essentially as shown.

Preferablyjournaled in or upon the walls of the receiver 16 is the shaft 25, carrying a tailpulley 26 of an endless elevator or drag belt 27, of any suitable construction, which also passes over a driving-pulley 28 upon the driving-shaft 29, suitably mounted in bearings 30, preferably formed on or connected with the main frame 1 of the machine, substantially as shown, and upon the drivingshaft 29 is secured a sprocket-wheel 31, chained to a sprocket-wheel 32 on the propelling-shaft 11 of the machine, whereby motion or travel is imparted to the endless conveyer or drag belt 27, as will be readily understood.

Formed on or connected with the frame 1 is a hanger-frame or depending supports 33, preferably provided with guideways 34, constructed to receive wheels or rollers 35, carried by an extensible or movable frame 36, in one end of which is preferably mounted a shaft 37, carrrying a driving-pulley 38 and provided with a spur gear-wheel 39, meshing with a driving-pinion 40 on a driving-shaft 41 having flexible driving connection 42 with the motor 6, substantially as illustrated, by means of which motion is imparted to the driving-pulley 38, as will be readily understood.

In the opposite end of the movable frame 36 is a tail-pulley 43, and mounted in said frame and intermediate of the driving and tail pulleys 37 and 43 are troughing-idlers 44, whereover passes an'endless belt or conveyer 45, adapted to receive the filtering material discharged thereupon by the drag-belt 27, substantially as subsequently more fully explained.

The machine is preferably guided or directed by means of a handle or other device 46, connected with a yoke or extension 47 of the frame 1 of the machine, the operator walking upon the filter in the rear of the machine for this purpose, and deflecting-pl ates 48 may be mounted upon one or both sides of the endless conveyer and beneath the discharging end of the drag-belt or elevator 27 for the purpose of directing the material discharged by the latter upon the endless conv eyer.

The operation of the foregoing invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following explanation thereof.

The motor 6 is started, thereby imparting motion to the gear 9 on the driving-shaft thereof, which gear meshes with the gear 10 on the propelling-shaft 11, carrying a sprocketwheel 13, chained to the sprocket-wheel 15 on one of the supporting-shafts 2, carrying the sets of sprocket-wheels 3, over which tray el the endless sprocket-chains 4, thereby imparting motion or travel to the machine, preferably by running the motor at a slow rate of speed when the machine is traveling in a forward direction or is operating and at a high rate of speed when the motor 6 has been reversed and the machine is being. backed up.

The filtering material may be conveyed to the machine preferably through the flexible connection 22 in communication with the source of supply, and water under pressure is preferably employed as a vehicle or conveying medium for such conveyance, and the water and filtering material are discharged into the receiver from the spout 24 and gravitate to the bottom of the receiver, where the filtering material is taken up by the dragbelt or endless elevator 27 and discharged over the discharging end of the receiver upon the endless conveyer 45, which conveys and discharges the material at a distance from the machine or at a desired point or place during the travel of the machine.

WVater used to convey the filtering material to the machine passes up over the weir 19 into the trough or conduit and out, or escapes through the outlet 20 and the connections 21 to the place of deposit.

Referring to Fig. 3'of the drawings, there is illustrated a modified form of construction hereinbefore described and shown embodying a supporting or traction portion 52, in the sides 53 whereof are mounted or journaled shafts 2, one whereof is preferably adjustable, as illustrated at 54, and upon said shafts are mounted sets of sprocket-wheels 3, over which pass sprocket-chains 4, carrying strips or slats 5, which may be with or without resilient facings or attachments.

Formed on or connected with the upper side of the traction or supporting portion 52 is a turn-table 55 of any suitable construction, the upper member of which is prefer ably provided with peripheral teeth 56, constructed to be engaged by a worm 57, revolu- ITO bly mounted in bearings 58, desirably secured to the supporting or traction portion 52, and the worm-shaft 59 may be provided with a crank 60 for the operation thereof.

Secured upon the upper member of the turn-table is a receiver or hopper 16, desirably constructed with inclined sides 17, and within the receiver 16 is suit ably mounted an endless elevator or drag-belt 27, passing over a driving-pulley 28 and over a tail-pulley (not shown) preferably located near the lower portion or bottom receiver, and upon the shaft 29 of the driving-pulley 28 is secured a sprocket 31, chained to a sprocket 32, mounted on the shaft 61, operated through reduction-gearing by the motor 6,

. having suitable connection 62 with the source ofelectrical supply. (N oti shown.)

erably mounted a partial partition-plate 18, to which is connected a weir 19, and in the side of the receiver is formed an outlet 20, around which is connected an outlet-pipe 21, communicating with the place of deposit, and an inlet-pipe 22 is preferably connected with a spout or nozzle 24, whereby the filtering material conveyed by a fluid vehicle, preferably under pressure, is discharged into the receiver between the partial partition 18 and the inclined side 17 thereof, and the filtering material settles to the bottom of the receiver, while the fluid vehicle or conveying element weirs up over the weir 19 and passes out through the outlet-pipe 21 substantially as before explained.

The machine is preferably propelled by means of an electric motor 63, driving suitable reduction-gears inclosed in a casing 6 1, whereby motion is imparted to a propellingshaft 65, carrying a sprocket 66, chained to a sprocket 15 on one of the supporting-shafts 2 of the supporting-wheels 3, carrying the endless sprocket-chain 4, to whichare connected the slats or strips 5, substantially as before explained.

The machine may be guided or operated by means of a handle 16, connected with a yoke 47, attached to the supporting portion or traction device, substantially as illustrated.

The operation of the invention 1llustrated in Fig. 3 will be readily understood from the foregoing description when taken in connection with the accompanying drawings, and

further explanation thereof will not be required further than to say that the distribution of the material is effected directly over the side of the receiver by the action of the drag-belt 27 the receiver being rotated into the desired position by means of the handle or crank 60, as will be readily understood.
